Question

Short conclusion on map half page

Answer 1

The maps presented in this monograph suggest just a few of the numerous ways that demographers can use contour maps to clearly, efficiently, and simultaneously display both persistent global and prominent local patterns in population rates or levels over two dimensions. In particular, contour maps can strikingly reveal the interaction between age, period, and cohort patterns. By using small multiples, computer movies, or ratio surfaces demographers can use the maps to gain access to several dimensions.
